Trix is a brand of breakfast cereal made by General Mills in Minneapolis, Minnesota for the North American market and by Cereal Partners elsewhere in the world. The cereal consists of Vanilla-flavored, sweetened, ground-corn pieces. They were originally spherical cereal pieces, but in 1991, were changed to puffed fruit-shaped pieces. In 2006, they reverted to their original shape in the United States and some other places; in Mexico they kept the fruit shape.
